05/2018 is Alexa ranking really meaningful?
Not really sure about meaning of Alexa Ranking in this context. google.com and amazon.com has nothing to do with its Subsidiaries business: AWC and GCP — Preceding unsigned comment added by Tech201805 (talk • contribs) 12:52, 25 May 2018 (UTC)


 * That was my impression too. IMHO this is not useful at all. 2A01:CB04:116:49EB:0:0:0:1003 (talk) 10:15, 13 May 2022 (UTC)
 * Went ahead and removed that column. It's a) not encyclographically relevant (a meaningless statistic describing something different than the subject altogether) and b) has a high probability to be misinterpreted as a measure of size (which it clearly is not).

What is GeoGrid
One section mentions "GeoGrid" in conjunction with OpenStack. I couldn't find mention of it on the web.

Needs to be reorganized
It is unclear to me what the table headers mean.


 * "As a service": Does this mean that it requires no installation? They all do, except that some are offered by their sponsoring companies as paid services.


 * "Supported Hosts": What is the difference between running on Linux or Windows and running on Bare Metal?


 * "Supported Clients": It's all confused. For example, AppScale does not run Vmware, Xen, or KVM. AppScale runs under Vmware, Xen, or KVM.


 * "Features": the headers are defined ambiguously. For example, the way that AppScale supports S3 is different in nature than the way Eucalyptus supports S3.

I think part of the problem is that we are carelessly mixing both Platform as a Service software and Infrastructure as a Service software.

needs work
Comparing Platform as a Service software (e.g. openshift) and Infrastructure as a Service software (OVirt, Opennebula, etc) based on the same properties does not seem to be fair or useful. Probably the article should break down to comparisons in those categories or focus on one. --Kozka (talk) 19:44, 12 May 2013 (UTC)

+1 - mixing PaaS and IaaS here makes this messy and confusing. — Preceding unsigned comment added by Randybias (talk • contribs) 12:03, 12 July 2013 (UTC)

This article appears extremely biased toward public cloud providers and Open software
Cloud services and the providers listed are only those that provide public services. The tools and capabilities noted are a developers list of cloud features, not a cloud comparision. The services they offer (IaaS, PaaS, etc.) are a factor also. Arguably, Salesforce.com is a major SaaS player, and never mentioned as a community cloud provider of SaaS.

The definition of cloud remains arguable, but the NIST definition illustrates a broader defnition consisting of
 * Public Cloud (which is partially covered in this article from a developer's point of view);


 * The current article omits vendors with major market share such as Savvis, HPcloud, and many others.


 * Community Cloud - A listing of those services with federated approach, perhaps like Microsoft Office 365.


 * Private Cloud - This is ignored completely, with many cloud products of major market share ignored:
 * VCE (consortium of VMware, Cisco and EMC),
 * HP CloudSystem,
 * IBM PureSystem,
 * Hitachi,
 * Fujitsu,
 * and many others.

Arguably, there are compontentized version of cloud systems by VMware, Cisco, Microsoft Opalis, and others that yield cloud results. The OpenStack initiative is yielding a build your own cloud stack, and the major players in cloud offerings are moving to support that as a standard. As Cloud comparison, these should not be a developer's view of the cloud, but a consumer's view primarily. Compare features such as infrastructure supported (Servers: IBM blades, IBM Aix, HP Blades, HP Proliant, Intelxxx, Sun xxx, Fujitsu xxx, etc.), Storage (EMC SAN, Hitachi SAN, HP 3Par, IBM SAN, NetApp NAS, etc), Network (Cisco, HP Procurve, etc), Management tools, Provisioning tools, support for virtualization (VMware, HyperV, KVM), etc. This is what I would expect in a comparison. The industry analysts like Forrester, Gardner, etc. look at market share, features, and various cloud capabilities as they compare the cloud providers, I would suggest the same. Look at this Porter Consulting paper is the reference paper for gauges for cloud comparisions for cloud: Ken L (talk) 17:14, 24 October 2013 (UTC)

Cloud Computing utilities
Reading the "Cloud Computing utilities" section gives a kitchen sink feeling. Formats like JSON or SOAP, database concepts like ACID and BASE have very little if any relationship with cloud computing. --K0zka (talk) 17:33, 26 February 2015 (UTC)

OpenStack does not support Windows
This article is inaccurate in general. Eucalyptus can run on bare metal, OpenNebula cannot? OpenShift supports Linux, VMware, Xen, and KVM guests? as guests? Cloud Foundry supports virtual machines as guests too? Cloud Foundry is platform-as-a-service, OpenShift is only for containers - WorldQuestioneer (talk) 14:45, 20 January 2021 (UTC)

IaaS comparison table makes no sense
As mentioned above, the Alexa rank is not very meaningful in this context. "SMTP Support", also is a very strange criterion for comparison, of all IaaS features. "IOPS Guaranteed minimum" - it's one of so many aspects to compare block storages. AWS "no critical bugs", Azure "there were some critical bugs" - what is this supposed to mean?

Add Linode?

Negligent security Azure?
Any breaches are serious, but other providers on the list have had beaches as well. It's definitely disingenuous to claim they're platform is overall insecure based on the public statement of 1 senator (however much we may agree with him.) And citing the same public statement twice doesn't indicate broader support for the claim.

Azure still provides DoD approved services allowed for usage by government in the US (the same country as the senator), so I think we need some stronger evidence if we're trying to refute that here.

Instead of reverting, I propose eliminating the column. It's very weird to have a true/false color value. All providers have "security" of varying sorts for their various services. (Not the only problem with this article. E.g. Many of the IaaS providers also offer a huge array of PaaS services. Jtrnp (talk) 23:09, 28 January 2024 (UTC)
